HTA Codes of Practice and Standards

Our Codes of Practice and Standards provide practical guidance to professionals carrying out activities within the scope of the HTA’s remit. 

Code A: Guiding principles and the fundamental principle of consent, is the overarching Code and contains information that is applicable to all establishments and professionals operating under our governing legislation.

In combination, this Code and the sector-specific Codes aim to provide anyone undertaking activities relevant to each sector with a reference source which gives practical advice on the minimum steps necessary to comply with the relevant legislation and HTA policy.

Our suite of Codes were published in April 2017, which was the last major review of the documents since 2009.

We have published our Codes of Practice and associated Standards to ensure that:
  • they reflect our current interpretation of the law and regulatory practice;
  • the Standards are fit for purpose; and
  • the Codes and Standards make our regulatory requirements clear, while minimising regulatory burden where possible.

The HTA's Code of Practice for organ donation to support the Human Transplantation (Wales) Act 2013 was unaffected by the 2017 review.
